More Information
Summary:Sealing strip element (1) for sealing a gap (5) between two components (2a,2b) of a gas-turbine installation, and extends along a longitudinal direction (21) and has a contoured cross section in a ribbed central region (10). The sealing strip element extends along the longitudinal direction (21), wherein at least one of the first main surface (23) and the second main surface (24) comprises a riffle structure, wherein the riffle structure comprises multiple teeth extending substantially from the first strip end (6a) to the second strip end (6b) along a substantially straight line while establishing chutes (7) between them, wherein at least one dam (30, 32) is provided at at least one strip end of the sealing strip element (1), the dam (30) closes the respective chute at the respective strip end (6a, 6b) of the sealing strip element (1) for reducing chute leakage flow.
